RAILWAY BUMPING-POST.

Application filed December 8, 1913.

To all 'whom it may concern:

Be it known that I, `W1LLIAM H. Minna, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Railway Bumping-Posts, of which the following is a specification.

This invention relates to improvements in railway bumping posts.

The main object of the invention is to provide a substantial and extremely rigid bumping post for railway service which is adapted to withstand heavy shocks without danger yof injury and which may be constructed with relatively small expense.

Another object of the invention is to provide a railway bumping post made of reinforced concrete and having a shell embedded therein, which shell is adapted to removably contain any suitable shock absorbing mechanism or cushioning device.

The invention furthermore consists in the improvements in the parts and devices and in the novel combinations of the parts and devices herein shown, described or claimed.

In the drawing forming a part of this specification, Figure 1 is a central, longitudinal, vertical section of a bumping post embodying my improvements and Fig. 2 is a vertical section and part elevation taken substantially on the line 2-2 of Fig. 1.

In said drawing the improved bumping post is shown as comprised of an abutment 0f concrete 10 having the lower portion thereof embedded within the earth and provided with a vertical front face 11. rlhe concrete has embedded therein at its front end, a cylindrical shell 12 of steel or other suitable material, which shell is open at its forward end and is provided with a flanged ring 13 removably held in place by a p lurality of nuts and bolts 14, said ring being adapted to retain a suitable shock absorbing or cushioning device designated generally by the reference 15. The forward end of the shock absorbing device extends outwardly beyond the front wall of the concrete abutment and is so located relatively to the track rails 16 and the bumper or coupler of cars as to be properly engaged when the car is backed up against the bumper post. The shell 12 is provided with a rear wall 1 7 suitably secured thereto and against which the rear end of the shock absorbing device 15 abuts. The rear portion of the shell 12 and Specification of Letters Patent.

serial No. 805,249.

the back wall 17 thereof are embedded in neat cement indicated by the reference 18. Extending rearwardly from the back wall 17 to the rear of the concrete abutment is a hollow tube 19 open at both ends whereby a bar or other suitable device may be inserted therethrough to assist in removing the shock absorbing device at any time desired and after the flanged ring 13 has been removed. The concrete abutment is reinforced by a plurality of vertically extending l'lV-rails 20 located to the rear of the shell and resist longitudinal and lateral thrusts. A plurality of inverted, substantially U-shaped, sets of reinforcing bars 21 and 22 are also employed. rIhe bars composing the set 21 extend over and around the shell 12 and have their lower ends turned inwardly as indicated at 23. The bars composing the set 22 are somewhat longer than the bars composing the set 21 and are spaced farther from the shell, the lower ends thereof being turned outwardly as indicated at 24C. The sets of reinforcing bars 21 and 22 resist any tendency of the concrete being split when radial thrusts are exerted against the shell 12.

From the foregoing description it will be seen that I have provided a railway bumping post of solid construction in which is adapted to be placed shock absorbing devices of various types and one that is adapted to resist and prevent any displacement of the shock absorbing device, since the latter is contained within a shell encompassed on all sides by suitably reinforced concrete.

Although I have herein shown and described what I now consider the preferred embodiment of my improvement, yet it will be understood that various changes and modifications may be made without departing from the spirit of the invention, and all such changes and modiiications are contemplated as come within the scope of the claims appended hereto.

I claim:

1. A railway bumping post having a reinforced concrete abutment, said abutment having a recess therein at its forward end within which is adapted to be placed a shock absorbing mechanism, said abutment having an opening therein extending from said recess to the rear end of the abutment whereby the interior of said recess is accessible from the rear of the abutment for the purpose of engaging the shock absorbing mechanism having an external annular flange and em- 10 Within the recess to facilitate removal of the bedded in a section of neat cement. mechanism.
